STANCHION FOR SUPPORTING BARRIER RAILS.

Application filed Aprilia, 1922. Serial No. 552,733.

To all whom it may concern:

Be it known that I, JOHN JAMES FAIR BAmN, a citizen of the United State-s, and resident of Roosevelt, in the county of Nassau and State of NewYork, have invented certain new and useful Improvements in Stanchions for Supporting Barrier Rails, of which the following is a specification.

This invention relates to stanchions for supporting barrier rails at street entrances and the like.

The object of my invention is to provide a stanchion of simple, durable and efiicient construction having a sectional base whereof the members can be readily set and locked in open position to provide a substantial supporting element, o r can be as readily released, collapsed and re-locked for convenience of packing and transportation, and havingy also a head portion embodying spaced-apart swiveled members adapted to receive and supportthe ends of bars or rails. In practice a plurality of the stanchions are erected at the desired location, and the ends of the bars or rails are supported by and upon the swiveled members of the respective stanchion heads, such members by virtue of their swivel mounting enabling the arrangement of the stanchions to support the bars or rails in alinement or in angular relation to each other as desired, and thus provide a fence or barrier of suitable shape to meet varying conditions; and also permitting any bar to be readiljT removed at one end from the adjacent swiveled member and bodilyv swung about an axis at its opposite end, so as to provide a suitable breach or opening for the passage of vehicles, all as will be hereinafter described and claimed.

In the drawings- Figure 1 is a side elevation of a stanchion embodying my invention, showing the device as erected and supporting the adjacent ends of two bars or rails.

Fig. 2 is an end elevation of the stanchion.

Fig. 3 is a transverse section through the standard, on the line 3-3 of Fig. 1.

Fig. 4 is a vertical section through the basal portion of the standard showing the upper base section as positioned longitudinally upon the lower section.

Fig. 5 is a vertical section of one of the swivel clips and its support.

Fig. 6 s a plan of several stanchions and bars or rails arranged to provide an irregular fence or barrier..

Referring to the drawings, 10 designates a substantial standard, preferably a metal tube, of suitable height for its intended pur.y

pose. The lower end of the standard is screw-threaded, as at 11, and a pair of centrally perforated bar sections 12, 13 are applied thereto. The lower sectiony 12 is clamped to the standard by lower and upper nuts 14, 15 on the threaded portion, and the foot of the standard is upset 0r swaged against the nut 11i in a manner to v loclrthe section 12 rigidly in place. The upper section 13 is freelyk rotatable on the standard, and the latter is provided with Va clamp nut 16 which may be screwed hard upon the section 13 in order to lock it rmly upon the standard. The two bar sections are formed at their extremities with depending feet 17, the upper section being slightly longer than the lower section in order that the upper may be swung into parallelism with or at right angles to the lower section. The clamp nut 16 is preferably provided with a projecting arm 18 to facilitate the turning of the nut either to lock or to release the upper bar section.

By this construction it will be seen that the two bar sections are permanently mounted on the standard, the lower section being xed and the upper section being rotatable to position it at'right angles or 'parallell to the lower section, as desired. The section` 13 when it is set at right angles to the lower section can be rigidly clamped in place by the nut 16, the two sections thus providing a substantial supporting base.` Further, the upper section can be readily released by properly turning the clamp nut, and then can be swung into parallelism with and` locked upon the lower section, the two sections thus occupying small compass for convenience of pac-king and transportation.

The standard is equipped with a head portion, preferably constructed of tube fittings, comprising relatively short oppositely eX- tending arms 19 fast to the upper end of the standard and parallel to the fixed base section, and tip-turned elbows 20 upon which Etl-shaped clips 21 are swiveled for horizontal rotation. in the present instance the basal portion of each clip is perforated, as at 22, and rotatably fitted to a vertical threaded stud Q3 on the outer end of the adjacent arm, the stud being provided with a cap nut 24 to prevent displacement of the clip. Each clip is of appropriate internal width and height to receive and firmly support the end of a'bar or rail, as 25.

The above described arrangement of the arms E19 and their appurtenances in respect to the fixed base section 12 permits the ready packing of the stanchion when vthe base sections are in parallel relation to eachl other mit the arrangement ot the stanchions to as previously mentioned.

To use the improved stanchion above described two or more of thel same areerected in spaced relation to eachv othery in the vicinity of the opening or way to be blocked,

as, for example, the entrance to a street, the number and the relative positions Lof the stanchions employed depending upon the width or shape of the space to be obstructed. The ends of the bar or bars 25 `are then ap- `plied. tol and supported in the clips on the arms of the stancliionsl .adjacent thereto, which clips, being-rotatable, not onlypersupport the bars in longitudinal alinement or in angular or zig-zag relatioii'in'order to provide a fence'or barrier of variable shape and bodily yswung about the axis of the clip as yconditions may require, as indicated in Fig. 6, but also permit any bar to be removed at one of its ends from the supporting clip at its opposite end, similarly to a gate, in order to providea breach or opening jor the passage of va vehicle, without the necessity of entirely dismountingabar or bars. (See dotted lines in `Fig. 6.) n d lt is to be understood that my invention is not limited to the detailsoi construction herein disclosed, as the same may be inodiv fied within the principle oi the ,invention and the scope of the appended claims.

" I claim l.A ln a stanchion for the purpose described, a standard, and a isupporting base thereon, said base comprising "two bar sectionssuperposed one on the other, the lower section being, rigidly fixed intermediate its ends to the foot of the standard 'and the upper section being rotatably yi'noun'ted intermediate its ends on the standard, and locking and releasing means for the rotatable section. ,A

2. In a stanchion for the purpose described, a standard screw-threaded atfits lower end, two perforated bar sections fitted one above the other to such lower end, the upper section being rotatable, nuts mounted on the threaded portion to embrace the lower section and lock it rigidly to 'the standard, and a clamp nut fittedv to the threaded portion of the standardV above the upper section and operable to lock the latter section in any.

position to which it may be turned in rela-` tion to the lowervsectio-n. v

3i.. ln av stanchion for' 'the purpose described, a standard a supporting .base thereior comprising` two bar sections superposed one on the other, one section beingiixed andextending arms on the' upper end of the said standard, and up-standing lsupporting clips' independently swiveled lon vertical axes on the respective arms', said arms being substantially parallel to the iixed bar section l` 5. in a stanchion for `the purpose'fdescribed, a standard screw-threaded at its lower end, two perforated bar sections itted one above the other tosuch lower end, the upper section being rotatable, niitslfmounted. on the lthreaded portioiifto embrace the portion'of` rthe standard abovev the upper y lower section and lock it, rigidly to' the" 'l f standard, a'clamp nut iitted'tothe 'threaded section and operable to lock or releasethe,4 latter section, laterally extending` arms on ,d

the upper end lof the said standard,land upstanding `supporting clips independently swiveled on vertical axes on 4the respective arms, saidv arms being substantially parallel to the fixed bar section.
